To keep your historical performance data and migrate your MySQL database to SQL Server, please complete the following steps:

1. Stop the up.time data collector:  

   Unix: # /etc/init.d/uptime_core stop  Windows: > net stop "up.time data collector"

2. Dump the database: > / scripts / fulldatabasedump 
3. Set up the SQL Server database.

4. Edit the uptime.conf file to point to the new database by commenting out the MySQL lines and uncommenting the SQL Server lines. 

   #dbDriver=com.mysql.jdbc.Driver   #dbType=mysql  #dbHostname=localhost   #dbPort=3308   #dbName=uptime   #dbUsername=uptime   #dbPassword=uptime       #example SQL Server configuration   dbDriver=net.sourceforge.jtds.jdbc.Driver   dbType=mssql  dbHostname=localhost   dbPort=1433   dbName=uptime   dbUsername=user   dbPassword=password

5. Stop the MySQL database: 

   Unix: # /etc/init.d/uptime_datastore stop  Windows: > net stop "up.time data store"

6. Initialize the database:

   > / resetdb --nodata really

7. Import the database to SQL Server:

   > / scripts / fulldatabaseimport

8. Start the data collector: 

   Unix: # /etc/init.d/uptime_core start  Windows: > net start "up.time data collector"
